At the commonsensical level of the manifest image, we seem to take for granted logical laws of all sorts, including classical logic (CL) and naive principles of truth and predication (TP), which, however, generate logical paradoxes such as the liar, Russell’s paradox and Curry’s paradox. The formal logic of the scientific image comes to the rescue by proposing many competing formal systems that restore consistency, by sacrificing either principles of CL or principles of TP. We wish to explore a different path, which aims at saving both CL and TP,…

We study different forms of ignorance and their correlations in a bi-modal logical language expressing the two modalities of knowledge and belief. In particular, we are mainly interested in clarifying which definitions of ignorance and which circumstances trigger higher-order forms of ignorance, inducing ignorance about ignorance and so on. To this aim, three ground conditions concerning knowledge and belief are presented, which may be seen as a cause of ignorance and can help us to identify the conditions enabling the emergence of higher-order forms of ignorance.

Doing metaphysics by building on empirical sciences is a very controversial matter. This paper outlines a middle road between the Scylla of denying the possibility of metaphysics and the Charybdis of doing metaphysics a priori. This is possible if, on the one hand, we accept a moderate form of scientific realism. On the other, we establish a logico-epistemological framework adequate to face the underdetermination of metaphysical theses with respect to our best scientific theories. The case of the debate between eternalism and presentism tests my perspective. In this case study,…

Stanford’s unconceived alternative argument is inductively based on the history of science and tells us that when a scientist is choosing a theory T1 at time t1 over a set of less promising alternatives, she is concurrently failing to conceive valid theoretical alternatives to T1, i.e., theories that will be accepted by a scientific community at later times, thus displacing T1. The aim of the present paper is to argue that the actual strength and reach of Stanford’s argument sensibly vary according to the status of the unconceived alternatives at…

The scientific enterprise enriches the debate about models. In particular, in the field of structural biology, a new deep-learning neural network system called AlphaFold has been applied for many purposes. It allows us to predict a protein’s structure with high accuracy. I will present the system in light of the discussion of structure representation and argue for a specific kind of representational relation holding between the predicted model structure and its target-system. By doing so, I will criticize the artifactual approach advanced by Knuuttila (2021) and present the features that…

In this paper, I will deal with the use of fictional models in the context of the realism vs antirealism debate. Specifically, I will argue that the explanatory role of fictional models can be accommodated by scientific realism. I will refer to the work of Alisa Bokulich, who has proposed a modification of realism in order to account for explanations employing fictional models. My own approach will be to offer an alternative: instead of a modification of realism, I will propose a modified notion of representation. Based on the work…

Realists and antirealists agree that different theories can be more or less empirically successful, even if they disagree on how to interpret this fact. Most of their arguments rely on how the notion of success is understood; still, few definitions of success are available, and their adequacy is doubtful. In this paper, we discuss some of these definitions and introduce a new measure of the success of a theory relative to a body of evidence aimed at overcoming some of their limitations. We moreover discuss how empirical success is connected…

Starting from some results of neuroscience, and especially of Embodied Cognition, I’ll discuss the problem of the intelligent use of tools, as a useful perspective under which to investigate the link between common knowledge and scientific knowledge. The philosophical question from which I shall start my reflection is the following: how do we represent reality to ourselves when we intervene on it through the intelligent use of a tool? The answer to this problem will be developed in two fundamental steps. 1. The problem of the intelligent use of tools…

The currently mainstream view is that, in normal conditions, our perceptual representations are largely accurate, as natural selection tends to favor epistemically reliable perceptual systems. This latter assumption has been questioned by Donald Hoffman and his collaborators by drawing on the formal tools of evolutionary game theory. According to their model, an organism whose visual system were tuned to objective reality would be driven to extinction. We argue that their model fails to take environmental modifications into due account, and we show that, once such changes are incorporated into the…
